The excretion of hypertonic urine in humans is associated best with the:
Correct answer: C. Loop of Henle
- A. Glomerular capsule
- B. Proximal convoluted tubule
- C. Loop of Henle
- D. Distal convoluted tubule
Explanation
The Loop of Henle is responsible for creating a concentration gradient in the medulla of the kidney, enabling the production of hypertonic urine through the countercurrent multiplier system. This allows water to be reabsorbed in the collecting duct, concentrating the urine.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
